Title: Spring and seat assembly for ball valves
Inventor: STONE RALPH S
IPC: F16K/
Filed: 1988-12-29
Granted: 1993-06-15
Abstract: ABSTRACT      A spring for a top entry ball valve includes a generally "u"  shaped spring body with an open end.  The ball  valve includes a valve body with inlet and outlet flow passages communicating with a valve chamber.  A ball element is mounted in the valve chamber for rotation between open and closed  positions  relative  to  the  flow  passages.   A  seal element is mounted adjacent each flow passage with a sealing face  in opposed sealing relation to the ball  element.   A moveable seat assembly is located between the seal element and  the  valve  body  for maintaining  the  seal  element  in sealing relation to the ball element.  The spring is located between the moveable seat assembly and the valve body and is adapted to  urge  the moveable  seat  assembly  and  the  seal element toward the ball element.

Abstract: METHOD AND APPARATUS FOR REMOTE SIGNAL ENTRY   INTO MEASUREMENT WHILE DRILLING SYSTEM          Abstract of the Invention:   A method and apparatus for remote signal entry of control or data information from an equipment operator into an MWD system is presented.  In accordance with an important feature of the present invention, the magnetometer, which is typically present in commercial MWD systems, is used as a communications channel for remote (e.g. wireless) transfer of data and/or control commands into the MWD tool.  The present invention functions by replacing the direct electrical RS232 coupling with a wireless magnetic link.  The invention uses the RS232 output of the operator's computer to drive its power amplifier which in turn drives the field coils in a transmitters.  The axis of the field coils must be aligned with one of the sensitive axes of the magnetometer which, as mentioned, is a pre-existing part of the directional measurement system of the MWD apparatus.  Thus, the present invention overcomes the necessity in the prior art for a direct RS232 link up between the surface computer and the computer on the MWD tool.

Abstract: APPARATUS AND METHOD FOR PROCESSING SIMULTANEOUS RADIO FREQUENCY SIGNALS            Abstract In a signal processing system, a weighting function is applied to incoming signal pulses in response to a signal edge detector. A weighting function is applied both to the detected large signal pulse and to the time surrounding the signal  pulse within a window but at different times so that small signals,  if they occur overlapping in time with the leading or trailing edge of the detected large signal, are weighted independently of  the  large  signal.  The  weighting  functions  are multiplied with the incoming signals and then sent to conventional signal processing apparatus.

Granted: 1993-05-11
Abstract: ABSTRACT OF THE DISCLOSURE:       A method and apparatus  for mechanically  cleaning  freshly caught fish.  In an initial step for preparing a throat cut in a roundfish, the head thereof is bent backwards to an angle of about 30° relatively to the axis of the trunk to stretch the neck and isthmus of the fish.  A throat cut is then performed in two steps.          The first step of the throat cut is started at the ventral side of the fish, closely ahead of the front edge of the collar bones of the fish in order to cut the isthmus joining the head and the trunk.   Thereafter, the second step of the throat cut continues the first step of the cut by severing all the way into the gill cavity up to the spine and mainly following along the front edge of the collar bones. Subsequently,  a belly cut is made which permits the evisceration of the entrails of the fish intact.

Abstract: A method for collecting from a surface area crude oil or a similar highly viscous, tough and tacky material which covers the surface area as a layer, is characterised by consecutively separating volumes of the layer by means of a curtain of a fluid which under pressure is driven into the layer and has been heated to a temperature capable of lowering the high viscosity of the material in the volume, and applying suction to the material in the volume thus made low-viscous, for removing this volume of material from the area.A suction nozzle for carrying out this method has a suction channel (1) which is connectible to a suction conduit, a pressure fluid chamber (6) which has pressure fluid inlets and a first pressure fluid outlet (8, 9) surrounding the intake end of the suction channel.

Abstract: The invention concerns a method and an apparatus for measuring the meteorological visibility and the scattering of light. According to the method, a light pulse is emitted into the atmosphere via an optical transmit system (7, 9), the backscattered light returns via the optical transmit system (7, 9) after which its intensity and delay are measured. According to the invention, the waveform of the optical transmit pulse generated at the instant of its launching from within the apparatus is sensed in a manner that excludes any backscattered light originating from outside the measurement system, this signal is scaled for both its magnitude and phase so as to achieve a suitable feedback signal relative to the actual measurement signal and said feedback signal is subtracted from said measurement signal to avoid overloading of the receiver. <IMAGE>

Abstract: 582,737. Secret transmission. PATELHOLD PATENTVERWERTUNGS- & ELEKTRO-HOLDING AKT.-GES. April 5, 1944, No. 6377. Convention date, April 5, 1943. [Class 40 (iv)] In a system of secret telephony wherein the speech band is converted into a number of adjacent but transposed sub-bands of which the relative widths are constantly varying, the arrangement is such that at least one subband is inverted and at least one is not inverted. As shown in Fig. 4, the speech band e0 modulates successively a fixed frequency g1 and a varying frequency g2, the lower side-band being selected in each case to give the band e2. This then modulates a pair of frequencies g3, g4 spaced by the width of the band to give an inverted double-band e3 and also another pair of frequencies g5, g6 to give an erect doubleband e5. Complementary portions e4, e6 are selected from these double-bands and combined to form a double-band e7, from which the central portion is taken and shifted to produce a final band e10 comprising four subbands of varying width, two being erect and two inverted. In another arrangement of a similar character, different transpositions of the sub-bands are obtainable by a choice of carrier frequencies at the intermediate modulation stages. One or more of the sub-bands may be retarded ih relation to the remainder of the band ; for example, the selected portion e4 may be retarded by means of a telegraphone before combination with the portion e6. The speech band may be subjected to variable attenuation before scrambling. When the arrangement is applied to a multi-channel system, several speech channels may be grouped together for the purpose of scrambling.
